Born from duality, the timepiece displays two different time zones through its GMT feature. At the heart of the timepiece, the Hublot Unico manufacture movement HUB1251 is equipped with a patented proprietary module which enables the second time zone to be updated instantly by a push-button, allowing the local time to be read easily via the conventional main hand of the watch. The time at home is indicated using a second arrow-shaped hour hand, which integrates a day/night indicator and is set using the crown. True to the All Black concept, tone on tone, the signature of Yohji Yamamoto can be discovered at six o’clock.
